. Toall whom it may concern: I .Be it known that I, HERBERr C. LEONARD,

a. Citizen of the United States, and resident -of Acus'hnet, in the county of Bristol. land State of lS/Iassael1usetts,have invented certain new and useful Improvements in Maga- .illustrated is especially adapted to be at# the present invention is that a barrel is em? tached to a machine for making tacks, which machine is substantially the same as that illustrated and described'` in U. S. Letters Patent No. d551,279, issued December.10,1895.

Insome instances tack-making machines and nail-making machines of the character illustrated 1n the aforesaid patent have been provided with magazines for blank strips and with means for feeding theblank strips one by one from the magazine to the feedingmechanism. One characteristic feature of ployed to guide the blank strips to the working instrumentalities, and this barrel is provided with a longitudinal slot through which the blank strips may be inserted laterally. The magazine for the blank strips is disposed atone side ofthe barrel in such close relation t0' the barrel that a blank strip in moving from the magazine into the barrel does not have far to move, the lcngthof the movement being 'in no way dependent upon the length of the.l

strip. So far as I am aware, blank strips have never-before been inserted into va bar-A rel in this manner but have only been inserted into the. outer end of the barrel by endwise movement of the strip.- One advantage of providing the barrel with a slotv and of arranging' t e magazine at the side f the barrelfis that 4a blank stri may be very quickly placed i'n the barrel 1n position to be taken by the feeding mechanism. Another advantage is that much less fioor space is required than if the" magazine were arranged beyond the'outer end of the barrel.

The function of these cutters is to sever asmall piece from the delivery end of a blank'strip, which small piece is afterward'formed into a tack. The cutter c' is carried by .an arm a," .(see Fig. 24),.and the cutter b is carried by an arm b. 'lhes'e arms aremounted respectively on studs-c2 and'b2 aboutvwhieh they vhave a'short movement. The studs a2 and b2 are fixed in any desired manner inA a bed c '.which is supported by legs d, the bed and legs forming the main frame of the tack machine. -Upright pieces e extend upwardly from the bed to furnish bearings f for a.

prime power shaft g. This shaft isi-formed y or pi'ovided with cams a and' b3 which act' respectively upon tlicvarms a.and b' to de press the arms. The arms are held upwardly -against the cams by long leaf springs such asthat indicated inAFig. 1 at b4. The spring thus shown acts upon tli'e arm b', and a similar spring which acts' upon the arm a 'occupies the same relative position and is.con

e 'iled by the spring b. The cutting edges 5' or the cutters a and b are at their lower ends, 5

and they coperatc with avxed shear or cutter which is indicated at z/in Figs. 24: to 26.V A blank strip. isindicated in F ig. 24 at X, and it is fed step bystep from left to rightwith'. relation to that figure. Itsadvance movement is limited by a. fixed stop z`, Shown in Fig.- 24. The strip is jfed forward when the cutters are elevated,and when 'they a're depressed by their respective cams they sever ace for'ward end of the strip, as shown b Fig. 25. The severed piece. .indicated at X',

(See Figs. 3 and 4.) This carrier 'is niounted in suitable guidest) on a bed 60, and is reciprocated upon the bed toward and from the tack-forming'1 means. The connection j.'\etwee'n the jaw slide 46.and the semi-annu- 'lai" 'carrier 58 enables the feed barrel and the fin 57' tow oscillatc as hereinbefo'r'edescribed and atv the' same .time maintains operativ'e" connection wliereby-thejaws are movedlon- .gitudinallyin the barrel'.

This adjusting Ameans requires no detailed -de seription, since-it is within the province of e every mechanic to vprovide some-means for the purpose explained.

The rocker arm 63 has an arm 68 whereby the necessary movement is caused to oscillate .the barrel. Atthe lower end of 'thearm 68 is a stud 69 which is adapted to be engaged onV one' side by one end of an operatlng rod 70, and on the other by a short piece. 71. The

members 70 and 71 are connected by a yoke 72, which yoke is adapted to rest upon the stud (39l when it is not otherwise supported.

Thelfother end of the rod 70 (see Fig. 1) is piVotally-connected to'an arm 73. 4VThe arm .73 is atlixe'd to` a rockshaft' 74 which is mounted suitable bearings carried by 'the legs of the tack machine. An arm 75, like-- A wise alixed to the ,rockshafh is connected by a link 7 6 to a crank pin7 7. `This crank pin pinion 80'on the prin'iefpeiver shaft g. '.lhe

Th-gear 78 is provided with a radial slot 8l in which thel crank pin'l isv adjustable. for determining the lngth; of' oscillatoryA movement of the feed"elixir-rel. ,This movement, as-prev-iously `sta1ed,is .180 degrees. .'As shown-by Fig. 3, the rod 70- is lifted out of engagement; with the st\ 1d69, thus interrupting operative.connection of the A'means' for. oscillating the barrel. The rod 70 is held in this position when the gripping jaws are movingback in ithe barrel and while a fresh .blank X is being linserted in 'the' barrel, after'whieh' the rodfis permitted to' dl'opjinto operativcengagement'with the stud 39. V'It remains in operative position diu'ing'fflle fi'ii'ward" movement of the; ip- ]'iing-jaws'in the barrel'. The rod 70 is lifted I -from operative position lbya rod 82 which is bcntat its; lower end to form a hook. The upper exi'd o'f the'rod 82 isv connected by a pin 8310 one arm of a bell crank 84. yThe bell crank'is mounted upon a' pivotstud 85. 'lhepin-l, as shownbv Fig. 3, is engaged Y and supported by alatc'hSfS, which latch is ailixed'to arockshaft 87... Aspring 88 which is connected to the arm86 serves to, hold the lwhich l. the `tripping member 91 strikes the roll 90 and 'retracts the latch 86 from under the pin 83, therebypermitting the operating rod to drop into operative engagement with the stud 69.' The bell crank 84.1 spivotal1v connected to one end `of a connecting rod 92,`

the other end of which, as shown' by`Fig. 2,

is pivotally connected toan arfm 93. This arm carries a roll 94 which stands-'1n the -path of a-secotd`tripping member 95 (see Figs. 1,-4 and 8) which is carried by the' cross piece 92. on the carrier 58. The func- `tion ofthe tripping member 95 is to liftthe rod 70 when the jaws in the barrel are retracted from the delivery end of the barrel. Thelpivot pin whereby'thelatch 91 is mounted upon thecross piece 92, is-indicated at 96; and the pivot pin ior the tripping member 95 is indicated at 97. AsA shown by Figs. 3 and 4, the tripping member'91is provided i with an ear 98, and the tripping member 95 'is provided with an ear 99, .the ears'being adapted 'to bear against the under sideofv the cross piece. These ears'fextend in op'-, osite directions. When thetripping memr95is movingtoward the tack machine it turns about its pivot 97 rides over the roll 94Jand drops into operative position after passing the roll. When it is moved in the opposite direction it engages and moves-the roll 9.4 with :the eilect of lifting the rod 70 out of engagement withthe stud 69. During .the movement away from the tack; machine the tripping member 91 rides overthe roll. -1

without producing anyv result,:afterwhich it drops into operative position ready-to withdraw the latch 86 from the pin 83 when the jaws are again movedl forward in the barrel. adaptedto-abut against the pin 83iwhen the The free .end of' the latch'86 operating rod 70 is in operative position;

and when the bell crank 84 is moved to lift the rod 70, the latch 86 is automaticallyI .moved`under the pin 83 .by the spring 88.

lWhen the parts are in the position shown by Fig. 3, 'the barrel is in position to 4re,-

vceive'a freshl blank. At this timethe barrel is held in the desired position by a weight i 100, ,'which weight is attached to one end of a cord 101. `The cord extends over a grooved roll`i102 and is connected to lthe'arm 68. shown by Fig. 3, anadjustable stopscrew A 104 which isthreaded in a boss 103 on the feed barrel is thus held against a'bosls 105 on the bearing 32. The stopscrew'104 vis acljusted to `'cause the-'opening 42 -'ofthe '-feed barrel to register'with. the bottom'strip in the magazine.

The mechanism for inserting the bianks" laterally into the feed'barrel.'comprisesv a plurality of pushers which/are operated in unison. -In thepresent instance there are three of'such pushers. 1n Figs. 1, 910 and 11, at 106. The construction ofpne of these pushersisfshown 1301 They are Vindicated i and andxsince` the con# -struction is similar in all of them .a description of oiie will suice. Each pusher 106is' i' aixed to a slide 107. The slide ismovable --transversely of the barrelfin- -afgroovc 108 formed in the bed 41. Tliepusher lies under the` column ObIankstrpS- in the magazine and is formed with .af shoulder 109 'which'is adaptedto engage gone edgef ofthebottom strip toV push 4the strip laterally. -Yielding lpressers *106* are provided, (see Figs. A9

andl) for keeping the blank'strp seated i firmly upon the pushers during the movement of the'striproml the magazine to the barrel. The pusher is connected to the slide- 107 a screw 110 and is formed with'a 'slot for the reception of the screw whereby it may: be, adjusted to position lthe\sl ioulder' 109 for blanks of various widths'. -Each slide 107 is provided with va stud 111 on its under side, the stud extending: through a 'slot` 112 in thejbed 41.' Each stud is -coniiected bya link 113 'to oneA arm of a 'bell crank 114. The' 'pivot-'studs' for the three bell cranks 'are indicatedrat 115.-' The three bell cranks are piyo'tally connected to a connectingrod 116 which has. a parallel moveiment. .An 'operating rod 117 connects the' rod 116 with an arm 118 (see Fig. 8). The` cam faces which are indicated respectively -at 124 and 125. AWhen the carrier is moving :i'way'from the delivery'. end of the' barrel and is nearthe end of such movement, the cam face 125'ongages the roll 123. the result `of which is a forward movement of .'the

'Thearm 154 is'near the deliveryend .the barrel and-is providedwith a lateralv 'extension '157 'which'carries arol1 158. At the opposite end of the-. rockshaft 4155 (s e'e* Fig. 8)- isan arm 159 which carries -a roll 160, and at a'suitable 'point betweenfthel ends is indicatedatll. (See FigjSu.) 1.. The function of the arm 15 9 is to rock the shaft .155 so asf; to Ashift the'clutchvlsleeve drive, or, in other words, from Vthesprocket sprocket wheels. 135-and 136, butrthe lnuo-'- 'wheel 136'to thesprocket .whel 135.-. This movement is effected byafcam srfacel62 formed upon the crosspieceI '92 which isv Vcarried bythe carrier 58.` The cam surface acts first to shift the' clutch sleeve from the reverse driveto neutral position between the mentum'of the carrier.j58 .and theparts 1 which move with itjfi'ssuiiicient to continue the reverse movement after' the poweris dis connected, because the movement 'whichis transmitted by 4the 'clutch'mecha'nism-is a' relatively. -rapid vmovement. Continued movement of the carrierV 58, due to-*mo-v mentum, causes the cam162 to shift the clutch 'sleeve 131 into engagement withthe sprocketwheel 135 so that power is'connect-v ed for driving the carrier forward'.

It will be remembered that oscillatory movement of the barrelceases shortly' after the feeding jaws begin to move backward,

and'that duringth' greater part ofthe back- .wardmovemcnt of the jawsvthe bari-clare- "inains in position to receive -a fresh blank.

There "the time 'whenthe forward/drive is connect eed. The feed jaws', during thisdrivelrever's- .mg operation, are held open bythe cam faces 54 on the inside of the barrel; and asl the -feed jaws be in to` move forward they pais on plpposite sides of the rearI-'end of the fresa in -positionto' gripjthe blank when; they pass outv ofjen'gagementfwith the cam .is no appreciable dwell'betweenfthe "time twhen the reverse drive is .disconnected and 'iii forward. remains -connected for an instant after. the fresh bla-hk has been grippediintil the forward `end of thelfr'esh blank is carried nearly'into position tob'e severed by the cutters' a, Z), il.. The power for ei'ecting the forward drive is, however, disconnected at this .'time. and 'thereafter the. jaws -are fedv forward by theweight hereinbefore mentioned 'but net yet described.

. fj Theoperation of disconnecting. the power duringthe forward movement of the jaws is eiected through the medium of the intermediate arm 161 'on therockshaft 155. This f arm 161, as shown by. Figs. 8and 8", is connected'by arlinkv 1 63 to an arm'164 onth'e 'oppositeside of the bed 60. Thejarm 164 vis pivotally.mounted'-uponaA stud 165 and has atA its upper en dfa mili-166 which is "adapted to be engaged by the cam-surface 12f1- on thecross piece which is carried by the carrier 58. This cam surface7 a's herein- .before.explained, engages aA rollv 122 Aforretra'cting the pushers by which afresh blank is deposited in the barrel. 'The cam surface, after retraoting the pushers, strikes the roll 166, thereby rocking the shaft. 155. This movement of the rockshaftshifts the clutch sleeve 131 from the forward drive vto its neutral position. The feed jaws are there' after carried forward-tuya' weight 167 which is suspendedby a cord 168, one end of which is anchored at 169 and 'the other end of which is attached to the under "stretch of the endless chain 128 at a suitable point of the 1atter.` The cord passes over an idle roll- 171whichis supported by thebracke't 66,'

and 'also passes around a sheave v170 with4 which the weight 167 '/rovided` The-j effect of the weight .is to raw the under stretch of the 'chain"aivayixfrom the tack machine, 'thereby'causing the upper stretch or' vthe chain to move toward' the tack machine. The carrier 58, being attached to the upper stretch ofthe' chain, is therefore carried toward the delivery end of 'thefbarrel bythe weight. e.

lVhen the cutters a :mdb of. the tack ma;

chine are elevated, the blank'strip is 'fed forward by Athe'weight until the forward end of the-strip abutsagainst 'the.. stopvz'. Then cutters descend and sever the end I weight; and thereafter `when 4the cutters rise their forward movement,' the clutch sleeve l 131 is shifted into 'engagement with the 'v ment, thereby Vactuatingl the arm 154i, 157

and shifting i has been so far retracted as to cause the cam structing and using the saine, although witheof from lthe jaw slide 46, a'nd the roll 158 sprocket wheel 136.'l The `endless chain 128 fin whichitmay bemade or all the modes' .of itsfuse within the scopeof the claims, I Aclaim:

This movement of the clutch sleeve: is occasioned by tlieeoperat-ion-of the tin 56 which projects which is carried by the rocker arm 154, 157 The movement 'of the rockshaft 155, which is occasioned by the cam surface 121 during theA forwardmovement ofthe carrier 58, places the roll 158 in the ath of movement of the fin 5G. 3 Consequent y, lwhen then is .moved forward as lfar as the ro'll'158, it -strikes'th'e roll during its oscillatory movethe clutch sleeve `131"fro'm its neutral position into engagement with the is thereupon driven/in the reversdirection at relatively high speed until the'v carrier 58 162 to strike the roll 160, as hereinbefore explained.
